The operation of the water treatment device according to the present invention configured as described above will be described.

The water treatment device is a device capable of taking out any one of purified water, cold water and mixed water according to a user's selection. Hereinafter, description will be given in the order of purified water extraction, cold water extraction and mixed water extraction.

Referring to FIG. 2, after the rotary takeout device 200 is rotated to extract the purified water, the takeout buttons 231 and 235 are selected. At this time, the controller 15 controls the three-way valve of the water supply line 20 so that the purified water of the water supply line 20 flows into the purified water extraction line 70. Therefore, the purified water is taken out from the rotary take-out apparatus 200.

In addition, after the rotary takeout device 200 is rotated to take out cold water, the takeout buttons 231 and 235 are selected. At this time, the controller 15 controls the three-way valve of the water supply line 20 to allow the purified water of the water supply line 20 to flow into the cold water supply line 40. The purified water of the cold water supply line 40 is cooled while passing through the heat exchange part 41. The controller 15 allows the cold water cooled in the heat exchanger 41 to flow through the cold water extraction line 80. Therefore, cold water is taken out from the rotary take-out apparatus 200.

In addition, the rotary take-out apparatus 200 is rotated to take out the mixed water and then the take-out buttons 231 and 235 are selected. At this time, the controller 15 controls the three-way valve of the water supply line 20 to allow the purified water of the water supply line 20 to be introduced into the cold water supply line 40.

In this case, the controller 15 controls the three-way valve of the cold water supply line 40 to allow the cold water of the cold water supply line 40 to flow into the mixing tank 60.

In addition, the controller 15 opens the vent valve 111 of the vent line 110 before opening the valve of the gas supply line 30 to discharge the gas not dissolved in the mixing tank 60 to the outside. . At this time, the internal pressure of the mixing tank 60 is significantly reduced.

In addition, the controller 15 opens the valve 31 of the gas supply line 30 so that the gases in the gas supply line 30 are mixed. At this time, since the pressure of the gas supply unit 40 is significantly higher than the pressure of the mixing tank 60, the gas of the gas supply unit 40 may be introduced into the mixing tank 60 without a separate driving source.

Gas and cold water are mixed in the mixing tank 60 to form mixed water, and the mixed water flows into the mixed water extraction line 90. Therefore, the mixed water is taken out in the rotary extractor 200.

A control method of the water treatment device according to the present invention configured as described above will be described.

5 is a flowchart illustrating a control method of a water treatment device according to the present invention.

Referring to FIG. 5, when the user grasps the handle 221 and rotates the rotating member 220, the magnet 245 corresponds to any one of the three sensors 241a-241c. In this case, a current is changed by the magnetic force of the magnet 245 in the sensors 241a-241c, and the controller 15 detects a current change of the sensors 241a-241c to rotate the position of the rotating member 220. It will be detected (S11).

Subsequently, the controller 15 determines whether the eject buttons 231 and 235 are selected (S12). In this case, when a user's finger or the like comes into contact with the ejection buttons 231 and 235, the controller 15 detects a change in capacitance generated from the PCB substrate 235 and determines whether the ejection buttons 231 and 235 are selected.

When the ejection buttons 231 and 235 are selected, the controller 15 determines whether the rotation member 220 is being rotated in the state where the ejection buttons 231 and 235 are selected (S13). At this time, the controller 15 determines that the rotating member 220 is being rotated when the sensors 241a-241c corresponding to the magnet 245 are changed or there is no corresponding sensor 241a-241c.

When it is determined that the rotary member 220 is being rotated in the state in which the ejection buttons 231 and 235 are selected, the controller 15 is connected to the purified water dispensing line 70, the cold water discharging line 80, and the mixed water discharging line 90. Close all installed on-off valves 71, 81, and 91 (S14).

Accordingly, even when the magnet 245 is instantaneously corresponding to the adjacent sensors 241a-241c while the rotating member 220 is rotated, the on / off valves 71, 81, and 91 corresponding to the adjacent sensors 241a-241c are rotated. Purified water, cold water or mixed water can be prevented from being taken out.

That is, when the rotating member 220 is rotated clockwise while the magnet 245 corresponds to the uppermost sensor 241a, the magnet 245 instantaneously corresponds to the sensor 241b located in the middle. After that, it corresponds to the sensor 241c located at the bottom. At this time, even if the magnet 245 corresponds to the intermediate sensor 241b in an instant, the control unit 15 does not open the on / off valve corresponding to the intermediate sensor 241b. In this case, while the rotating member 220 is rotated, it is possible to prevent the mixed water from being taken out briefly from the take-out port 222 located in the middle.

In addition, even if the magnet 245 corresponds to a sensor corresponding to the hot water dispensing line while the rotating member 220 is rotated, the controller 15 may prevent hot water from being blown out and prevent burns.

In addition, it is possible to prevent unnecessary waste of purified water, cold water or mixed water while the rotating member 220 is being rotated. In addition, the user's clothes can be prevented from splashing purified water, cold water or mixed water.

In addition, when all the open / close valves 71, 81, and 91 are closed, the controller 15 may display an error message through the display unit (S15).

On the other hand, if it is determined that the rotating member 220 is not rotated in the state that the take-out button (231, 235) is selected, the control unit 15 detects the sensors 241a-241c in which the current change has occurred, the purified water extraction line 70 In operation S16, the on / off valves of the on / off valves 71, 81, and 91 of the cold water extraction line 80 and the mixed water extraction line 90 are opened (S16).

The controller 15 determines whether the selection of the ejection buttons 231 and 235 is released (S17). In this case, when the user's finger or the like is removed from the ejection buttons 231 and 235, the controller 15 detects a change in capacitance generated from the PCB substrate 235 and determines deselection of the ejection buttons 231 and 235.

When the selection of the ejection buttons 231 and 235 is released, the control unit 15 closes the opening / closing valves 71, 81, and 91 (S18). Therefore, the user can take out purified water, cold water or mixed water as much as desired by adjusting the selection time of the ejection buttons 231 and 235.

On the other hand, if it is determined that the rotating member 220 is rotated while the water is withdrawn from one discharge port 222, the control unit 15 controls to continuously withdraw water from the discharge port 222 that was taken out. Can be.

For example, if it is determined that the rotating member 220 is rotated while the cold water is being discharged, the controller 15 allows the cold water to be continuously drawn even if the sensors 241a to 241c corresponding to the magnet 245 are changed. . Therefore, cold water and mixed water are taken out to a container, and it can prevent that cold water and mixed water mix.

In addition, when it is determined that the ejection buttons 231 and 235 are selected at the time of initial power supply, the control unit 15 opens / closes the valve 71 of the purified water dispensing line 70, the cold water discharging line 80, and the mixed water discharging line 90. , 81,91). Therefore, even if a part of the body unconsciously or inadvertently touches the ejection buttons 231 and 235 to supply the initial power, it is possible to prevent the water from being taken out. Therefore, it is possible to prevent the user's clothes from getting wet or the user getting burned.

In this case, the controller 15 may display an error message through the display unit. Then, after a predetermined time, the normal message may be displayed through the display unit.

The present invention can prevent water from being taken out while the rotary take-out device is rotated, and thus, there is a significant industrial applicability.
